Metal Gear Solid: Peace Walker

[walle]

Hello guys thank you for the work, I'm under the last version of PPSSP, and my problem with the game is I can't hear the voice of Kaz... I'm only at the begining... I can see the captions but I can't hear the sound/voice... Why? Obviously he's talking... (I mean not codecs) WHILE PLAYING... Like the instructions if you want. Cutscenes are fine, no problem with the sound, anyone else has this trouble?


Edit: it's the calls/radio And the sound is cracking while I play, is it this way for everybody? Or my iso is bad?
